As expected, a reduction of the corporate income tax rate from 35% to 20% is included in the GOP’s tax reform bill, a summary of which was released today. That rate cut would be a welcome development for workers, consumers, and corporate shareholders. It should be no surprise that the burden of the U.S. corporate income tax is not borne exclusively by owners of capital. In fact, it might hurt workers and consumers substantially while imposing relatively little burden on shareholders.

“As an accounting matter, every cent [of taxes] corporations pay comes from higher prices, lower wages, or lower payments to shareholders. The only question is which one.“

Cochrane quotes Lawrence Summers and Paul Krugman, both of whom are of the belief that the incidence of the corporate tax must fall primarily on capital and not on labor. That’s consistent with their view that a reduction in corporate taxes amounts to a gift to shareholders. But Cochrane isn’t at all convinced:

“The usual principle is that he or she bears the burden who can’t get out of the way. So, how much room do companies, as a whole, have to raise prices, lower wages, lower interest payments, or lower dividends?”

In fact, owners of capital can get out of the way. Capital is very mobile relative to labor. Here’s a counterfactual exercise Cochrane steps through in order to illustrate the implications of ownership bearing the incidence of the tax: if equity markets are efficient, share prices reflect all available information about the firm. If wages and product prices are unchanged after the imposition of the tax, then shareholders would suffer an immediate loss. Once the tax is discounted into share prices, there would be no further impact on current or future shareholders. Thus, future buyers of shares would escape the tax burden entirely. As a first approximation, the share price must fall to the point at which the ongoing return on the stock is restored to its value prior to imposition of the tax.

Cochrane notes that evidence on the reaction of stock prices to corporate tax changes is mixed at best, which implies that the incidence of corporate taxation falls more weakly on shareholders than many believe. That leaves consumers or workers to bear a significant part of the burden. Workers and consumers are mostly one and the same: economy-wide, higher prices mean lower real wages; lower wages also mean lower real wages. So I’ll continue to speak as if the incidence of the tax falls on either labor or capital, and we can leave aside consumers as a separate category. Cochrane says:

“It used to be thought that it was easy to lower payments to shareholders — ‘the supply of savings is inelastic’ — so that’s where the tax would come from. The newer consensus is that companies as a whole have very little power to pay less to investors, … so the corporate tax comes from lower wages or, equivalently, higher prices. Then, indirectly, reducing the corporate tax would increase capital, which would result in higher wages.”

Cochrane’s post and another on his blog were prompted by an earlier piece by Greg Mankiw showing that real wages, in an open economy, will have a strong negative response to a corporate tax increase. Here is the reasoning: the tax reduces the return earned from invested capital in the short run. Ideally, capital is deployed only up to the point at which its return no longer exceeds the opportunity cost needed to attract it. Given time to adjust, less capital must be deployed after the imposition of the tax in order to force the return on a marginal unit of capital back up to the given opportunity cost. That means less capital deployed per worker, and that, in turn, reduces labor productivity and wages.

Another issue addressed by Cochrane has to do with assertions that monopoly power in the corporate sector is a good rationale for a high tax on corporate income. You can easily convince me that the “average” firm in the corporate sector earns a positive margin over marginal cost. However, a microeconomic analysis of monopoly behavior by the entire corporate sector would be awkward, to say the least. Despite all that, Cochrane notes that monopolists have more power than firms in competitive sectors to raise prices, and monopsonists have more power to reduce wages. Therefore, the “tax the monopolists” line of argument does not suggest that labor will avoid a significant burden of a corporate tax. A safer bet is that firms in the U.S. corporate sector are price-takers in capital markets, but to some degree may be price-makers in product and labor markets.

Cochrane also emphasizes the inefficiency of the corporate tax as a redistributional mechanism, even if shareholders bear a significant share of its burden. It is still likely to harm workers via lost productivity, as discussed above. It is also true that many workers hold corporate equities in their retirement funds, so a corporate tax harms them directly in their dual role as owners of capital.

The cut in the corporate tax rate is but one element of many in the GOP bill, but a related provision is that so-called “pass-through” income, of the type earned via many privately-owned businesses, would be taxed at a maximum rate of 25%. These businesses generate more income than C-corporations. Currently, pass-through income is taxed as ordinary income, so capping the top rate at 25% represents a very large tax cut. As Alex Tabarrok points out at the last link, tax treatment should be neutral with respect to the form of business organization, but under the GOP bill, the effective gap between the top rate for pass-throughs versus corporate income would be even larger than it is now.

Critics of a reduction in corporate taxes should bear in mind that its incidence falls at least partly on labor, perhaps mainly on labor. The U.S. has the highest corporate tax rate in the industrialized world. That undermines U.S. competitiveness, as does the complexity of corporate tax rules. Tax planning and compliance burn up massive resources while drastically reducing the tax “take”, i.e., the revenue actually collected. The corporate income tax is something of a “show” tax that exists to appease populist and leftist elements in the electorate who consistently fail to recognize the unexpectedly nasty consequences of their own advocacy.

The protectionist foreign trade rhetoric issued by the major-party presidential candidates is intended to appeal to ignorant economic instincts. Donald Trump and Bernie Sanders come to mind most readily, but Ted Cruz and Hillary Clinton are jumping in with similar campaign positioning. The thrust of these populist, anti-trade appeals is that America is losing jobs to “unfair” foreign competition, an argument that distorts the very objective of trade: consumers take part in exchange in order to consume; they capture value from high quality, unique merchandise and competitive terms. Ultimately, producers engage in trade to gain the wherewithal to consume. Consumption is the real end-game.

It can be misleading to talk about “nations” engaging in trade with each other, despite the emphasis placed on trade agreements like NAFTA and TPP. In the first place, it is better to stress consumers and producers, rather than “nations”, because most foreign trade is private, cooperative activity, not national decision-making. But the candidates persist in characterizing trade as a “contest”. That misleading notion is what prompts governments to muck up the trade environment by imposing restrictions on the free flow of goods and services. Trade agreements have been heralded as great achievements, but they never approximate a regime of truly liberalized trade because the latter requires no formal agreement whatsoever, merely a hands-off approach by government. And trade agreements tend to entangle trade issues with other policy objectives, holding consumers hostage in the process.

We hear from opportunistic candidates that jobs are lost to trade with foreigners. But again, consumption, not “jobs” per se, is the real objective of economic activity. If domestic jobs are lost, it is generally because consumers judge the value produced inferior to what’s offered from abroad. American consumers should not be obliged to support inferior value, domestic market power unchecked by competition, monopoly prices and limited choices. Patriotic jingoism attempts to blind us from these economic imperatives.

The standard protectionist narrative is that foreign “nations” cheat on trade with the U.S. via currency manipulation, predatory pricing or “dumping”, “unfair” wages or other unfair labor practices. Do any of these objections to free trade hold water?

The “fairness” of foreign wages and labor practices is a matter of perspective. Wages cannot be considered unfair merely because they are low relative to U.S. wages. Wages paid to workers by foreign exporters tend to be consistent with the standard of living in those societies, and they are often some of the best income opportunities available there. This is economic dynamism that lifts masses from the grips of poverty. It’s absurd to caste it as “exploitation”.

Is it “unfair” to competitors in the U.S.? Not if they know how to compete and are allowed to do so. Unfortunately, government regulatory policies in the U.S. often present obstacles to the competitiveness of domestic producers. This is well-illustrated by Daniel J. Ikenson of The CATO Institute in “Crucifying Trade For The Sins Of Domestic Policy“. He emphasizes that trade promotes economic growth, but when it causes job losses for some workers, U.S. economic policies make it difficult for those workers to find new jobs.

“Incentivize businesses to hire people to train them in exchange for their commitment to work for the company for a period of time. Reform a corporate tax system that currently discourages repatriation of an estimated $2 trillion of profits parked in U.S. corporate coffers abroad, deterring domestic investment, which is needed for job creation. Curb excessive and superfluous regulations that raise the costs of establishing and operating businesses without any marginal improvements in social, safety, environmental, or health outcomes. Permanently eliminate imports duties on intermediate goods to reduce production costs and make U.S.-based businesses more globally competitive. Advocate the retirement of protectionist occupational licensing practices.“

So-called “dumping” by foreign producers, or selling below cost, is an unsustainable practice, by definition. Pricing below cost is difficult to prove, especially if local wages are low and raw inputs are plentiful. If dumping can be proven, retaliation might feel good but would punish American consumers. A foreign producer might be subsidized by its government as a matter of industrial policy and economic planning, an unhealthy policy to begin with, and possibly to facilitate a long-run market advantage in foreign trade. The U.S. itself is thick with subsidized industry, however, so arguing for retaliation on those grounds is more than a little hypocritical.

I rarely quote Paul Krugman, but when I do, it’s from work he’s done as an actual economist, not as an agenda-driven pundit. So we have the following Krugman quote courtesy of Don Boudreaux:

“I believe that if the rhetoric that portrays international trade as a struggle continues to dominate the discourse, then policy debate will in the end be dominated by men like [James] Goldsmith, who are willing to take that rhetoric to its logical conclusion. That is, trade will be treated as war, and the current system of relatively open world markets will disintegrate because nobody but a few professors believes in the ideology of free trade.

And that will be a shame, because for all their faults the professors are right. The conflict among nations that so many policy intellectuals imagines prevails is an illusion; but it is an illusion that can destroy the reality of mutual gains from trade.“

The consequences of trade restrictions are higher prices, reduced production and reduced consumption, an undesirable combination of outcomes. This means higher prices of imported goods as well as domestic goods, whose producers will face less competition by virtue of the trade barriers. With reduced availability of imported goods, economic theory predicts that domestic producers will not fully meet the frustrated demands. This is a classic response of producers with monopoly power: restraint of trade. The negative consequences are compounded when foreign governments impose retaliatory measures against the U.S., harming American exporters.

A further misgiving expressed by politicians regarding free trade is that America’s trade deficit implies greater indebtedness to the rest of the world. This argument has been made by a few leftist economists who misunderstand the nature of direct investment, and who tend to think erroneously of economic outcomes as zero-sum. It’s true that foreign producers who receive dollars in exchange for goods often invest those proceeds in U.S. assets. A fairly small share of that investment is in debt issued by U.S. governments and private companies. But a much larger share is invested in U.S. equities and real assets, which are not U.S. debts. As Don Boudreaux points out, the domestic sellers of those assets generally reinvest in other U.S. assets, so private U.S. ownership of global capital is not diminished by increased foreign investment in the U.S.

An interesting aspect of the trade debate is that the dollar’s role as a global reserve currency implies that the U.S. must run a chronic trade deficit. The rest of the world uses dollars to trade goods and assets, but to acquire dollars, foreigners must sell things to holders of dollars in the U.S. This keeps the foreign exchange value of the dollar elevated, which makes imports cheaper to Americans and U.S. exports more costly to foreigners. Those dollars are a form of U.S. debt, but it is debt for which we should feel flattered, as long as confidence in the dollar remains. A diminished role for the dollar in world trade would lead to a surplus of dollars, undermining its value and promoting inflation in the U.S. Let’s hope for a gradual transition to that world.

Finally, the presidential candidates allege that foreign currency manipulation is another reason for American job losses. One prominent example occurred last year when China allowed the renminbi to decline to more realistic levels on foreign exchange markets. Donald Trump called this an unfair trade tactic, but apparently the People’s Bank felt that it couldn’t support the renminbi without undermining economic growth. The earlier dollar peg also helped to keep Chinese inflation in check. Contrary to Trump’s assertions, if China stopped manipulating its currency altogether, the renminbi would go even lower!

Beyond the opportunistic political arguments, the point is that central banks (including the U.S. Federal Reserve) manage their currencies to achieve a variety of objectives, not merely to promote exports. That is not an endorsement of such policies. It is an objective fact. Anyone can argue that a foreign currency is “too low” if their objective is to demonize a country and it’s exports to the U.S., but the assertion may not be grounded in facts as markets assess them.

The arguments against open trade policies are generally specious, hypocritical or grounded in a mentality of victimhood. Vibrant producers who are free of government restrictions should welcome the expanded markets available to them abroad and should not seek redress against competition via government protection. Liberalized trade has engendered tremendous economic benefits over the years, while protectionist policies have only brought severe contractions. Let’s be free and trade freely!

In advanced civilizations the period loosely called Alexandrian is usually associated with flexible morals, perfunctory religion, populist standards and cosmopolitan tastes, feminism, exotic cults, and the rapid turnover of high and low fads---in short, a falling away (which is all that decadence means) from the strictness of traditional rules, embodied in character and inforced from within. -- Jacques Barzun
